My computer has a gigabit Ethernet connection that is wired to a router configured as a DHCP server.
When plugging the cable, the computer gets its IP address and the netmask right, but do not assigns a gateway at all.
In syslog, I can see NetworkManager reading the right gateway from the DHCP response (and I checked with dhcpdump too), yet it does not keep it as the gateway, nor does it appear in the Gateway column of route -n output.
What could be happening here?
